After succesful login with default credentials, when browsing the UI we are getting this error:
_01 Authentication credentials were not provided._
It seems that some objects are getting 401:

If the page is reloaded, objects getting 401 can change.
Browse the application
Can't browse because of 401 errors
We have discovered something.
Our environment is:
Azure Load Balancer -> openshift router with 2 replicas
When router is scaled to 1 replica, AWX UI works without problem.
Reducing to one replica of the router on openshift (3.6) worked for us as well.
I have the same issue. Running awx on docker. I'm getting the same error 401. I'm not sure about replicas since I'm running it locally on my test machine. What is the underlying cause for the error?
Update: after some poking around and not finding anything, I spotted "power" button in the top right corner. I clicked it and was taken to the log in screen again. That solved it for me.
This should fix that up for you: https://github.com/ansible/awx/pull/969
@matburt I have the same issues as @luqmaanki running on stand alone docker host. Installed from master and 1.0.2.370 and have same issues. Docker host is behind ELB port 80
